1

TF card slot, only used with CM5 Lite to boot system, cannot be used as external storage for CM5

2

The RS485 circuit controls the Input and Output direction automatically, there’s no need to control it from within the software.

3

The default product without the CM5 does not include a Wi-Fi/BT module. You can include a CM5 that has the Wi-Fi/BT module at the Chipsee store during the ordering process.

Power Input

The CS-CM5-BOX industrial Pi PC can be powered by a wide range of input voltages: From 9V to 30V (supports optional 24V ignition signal) DC.

There are two DC input interfaces on this device: a 3-pin, 3.81mm screw terminal connector, and a 2.1mm DC input head. As shown in the figure below.

Power Input

Note that the “+” sign represents the positive power input, the “-” terminal is shorted to the ground.

Table 364 Power Connector

Power Input Definition
Pin Number	Definition	Description
Pin 1	Positive Input	DC Power Positive Terminal
Pin 2	Negative Input	DC Power Negative Terminal
Pin 3	Ground	Power System Ground

Note

The system ground “G” is connected to power negative “-” on board.

For a proper 2.1mm x 5.5mm x 9.5mm DC power connector, refer to the figure below:

DC Jack

Ignition Signal

The product has a “ignition signal” optional feature. By default the ignition signal is not installed. If you need this feature you can contact us when placing an order. In this setup, Pin 3 is the ignition signal pin.

The DC jack doesn’t support ignition signal.

To use this feature, apply a 24V DC input (relative to -) to Pin 3. If Pin 3 detects a low input voltage, the product will be shutdown. If Pin 3 detects a high input voltage, the product will be boot and running.

Attention

1. RS485_3 and RS485_5 can control the input and output direction automatically. There’s no need to control it from within the software.

2. The 120Ω match resistor for RS485 is NOT mounted by default.

3. The 120Ω match resistor for CAN is NOT mounted by default. Be sure to mount the match resistor when testing CAN.

4. RS485_3 and RS232_3 share UART3 and can’t work at the same time; RS485_5 and RS232_5 share UART5 and can’t work at the same time. Meaning the product provides 4 x RS232 + 0 x RS485, or 2 x RS232 + 2 x RS485, or 3 x RS232 + 1 x RS485.

GPIO Port

The CS-CM5-BOX industrial Pi PC has a 10 Pin 3.81mm GPIO Connector, as shown in the figure below. The table below gives details about the definition of every Pin.

Attention

1. In order to use the Isolated Output, you need to add an external Isolated Power to the VDD_ISO and GND_ISO. The power voltage should not exceed 24V.

2. The output current can achieve 500mA for every channel, but it also depends on the isolated power that is connected.

3. In order to use the Isolated Input, you need to add a signal to the ISO_InputX and GND_ISO. A 2.4KΩ resistor, as R6, has been added to limit the input current, as shown in the figure below. This resistor should work well for the 5-24V input signal. If your input signal is less than 5V, please change this input resistor. The reduced schematic is for reference purpose, if you need the precise resistor schematic, please contact us.

2. The USB3.0 comes directly from Raspberry Pi CM5.
3. When you connect this product to the HOST PC through the Type-C port, the USB2.0 type-A port will be disabled. As a result, the USB2.0 type-A port will not work until type-C is disconnected.

The product has one USB Type-C OTG connector that works as a slave by default. You can use it to establish a connection with the host PC and for downloading the system to the eMMC of CM5 module.

USB Type-C OTG Connector

Warning

1. Be careful not to touch surrounding electronic components accidentally while plugging in USB devices into the embedded Industrial PC version.
